Abstract
A method for measuring the adhesive strength of a hemostatic tissue patch. Two patches are attached to facing surfaces with a side that would normally seal tissue exposed. Liquid is placed on one of the patches to activate the hemostatic agent, the patches held together long enough to adhere to one another, and then pulled apart. The force necessary to detach them is measured, thereby providing a determination of the adhesive strength of the patch. In contrast to literature methods, the inventive method provides excellent reproducibility.
